Product Format, Transport and Storage

PassiveTec® Tunnel Liner boards are packed in secured edge-protected pallets and are identified with a sticker indicating: product name, production date, pallet number, and number of boards per pallet. All boards are stamped with production date.

PassiveTec® boards must be stored in their original pallets as delivered from the factory, under cover, not exposed to rain and in a dry place, and when removed from the pallet, they should be kept in an upright position.
